What is two-factor authentication?

Two-factor authentication provides a second layer of security to any type of login, requiring extra information or a physical device to log in, in addition to your password.

The factors may include:

• 

  Something you know a unique username and password

• 

  Something you have a smartphone with an app to approve authentication requests

• 

  Something you are biometrics - like your fingerprint or a retina scan

By choosing two different channels of authentication, you can protect user logins from remote attacks that may exploit stolen credentials.

For example, your first factor may be your password, while your second factor is sent via a push notification generated by an authentication mobile app on your smartphone that you must approve.
